Sennheiser Evolution Wireless EW-D SK / SKM-S Base Set (Y1-3 Frequency Range)

The Evolution Wireless Digital EW–DX system represents Sennheiser's most advanced wireless audio solution, designed to eliminate the complexities that have traditionally plagued professional wireless setups. This comprehensive bodypack base set includes the EW–DX SKM–S handheld transmitter with mute switch, EW–DX SK bodypack transmitter, EW–DX EM 2 rackmount receiver supporting two channels, and a pair of BA 70 rechargeable batteries. First launched in June 2021, the EW–DX series caters to voice applications, lectures, conferences, moderation duties, and live performances with unmatched reliability.

Setup becomes remarkably straightforward thanks to sophisticated automation tools built into the system. Auto Scan technology assigns channels automatically using an equidistant tuning grid, allowing you to pack more channels reliably whilst avoiding problematic intermodulation interference. The Sennheiser Smart Assist mobile app puts system control at your fingertips, while advanced software options like Wireless Systems Manager (WSM) and Sennheiser Control Cockpit provide detailed oversight in complex networked environments.

Built for scalability, the Evolution Wireless Digital platform grows alongside your requirements. Choose between 2–channel half–rack (9.5") or 4–channel full–rack (19") receivers to match current needs whilst maintaining expansion flexibility. Dante® network audio, Ethernet control ports, and AES–256 encryption enable secure IT network integration, whilst Link Density Mode maximises channel density in dedicated spaces. The system's digital UHF transmission combines with class–leading dynamic range and ultra–low latency, powered by Sennheiser's proprietary SePac audio codec and advanced conversion technology for exceptional audio transparency from capsule input through to system output.
